Licensed, insured, owner-operated general contractor serving Williamstown and Monroe Township. Get 35 years of remodeling and construction experience on every project.
Williamstown has grown a lot over the past few decades, mixing older farmhouses near Downe Avenue with the newer subdivisions that have filled in around Route 322 and Route 536. That variety means every remodeling contractor working here needs to handle different foundations, framing styles, and code requirements from one job to the next.
Many homes near Williamstown Lake and Scotland Run Park sit on lots with mature trees and slight grade changes, which affects everything from deck footings to drainage around a new patio or walkway. Basements in the older sections of town often have lower ceilings or dated wiring that need careful planning before a finishing project can begin.
As a residential contractor who has worked throughout Gloucester County since 1991, we bring that local knowledge to every basement renovation, garage conversion, and home addition we take on in Williamstown, including neighborhoods near Scotland Run Park and the newer developments along the Black Horse Pike.

Bowen Contracting handles the full range of home improvement work Williamstown homeowners ask for, from everyday repairs to complete basement remodels and garage conversions. Below is the full lineup of services we bring to town.
